词源 Etymology

thresher 源自古英语动词 rescan,意为"踩踏、击打",后演变为中古英语 threshen(脱粒)。加上表示"执行者"的后缀 -er,构成"进行脱粒的人或物"。在农业社会中,脱粒是收获后最关键的步骤之一,因此这个词在英语中有着悠久的历史。该词也被借用于命名长尾鲨(thresher shark),因为这种鲨鱼用长尾鳍猛击水面的动作酷似脱粒时的拍打。

  • 托马斯哈代(Thomas Hardy)的《德伯家的苔丝》(Tess of the d'Urbervilles)中详细描写了苔丝在脱粒机旁劳作的艰辛场景,thresher 在其中既是机器,也是工业化对乡村生活压迫的象征。
  • 约翰斯坦贝克(John Steinbeck)的《愤怒的葡萄》(The Grapes of Wrath)中多次提到机械化农具,包括脱粒机,反映了大萧条时期机器取代人力的社会变迁。
